Oil

Barbecue recipes usually call for call for olive oil, sesame oil, or in rarer instances, walnut or hazelnut oil. The olive oil should be extra virgin (the highest, most flavorful grade); the sesame oil should be dark (made with toasted sesame seeds)—look for Japanese and Korean sesame oils. Occasionally, you’ll be asked to use vegetable oil, because the flavor of a costlier oil would be lost among the other ingredients in a recipe.
